How to Extract Custom Entities in Text Content with JavaScript?

What is Custom Named Entity Recognition API?

Custom Named Entity Recognition (NER) API is a tool that enables users to build and deploy their own models for recognizing and extracting named entities from text such as names of people, organizations, locations, dates, or any other custom-defined categories.

A Custom NER API enables users to train models with their own labeled data, specifying the exact entities they want to extract.

This approach offers more precise and domain-specific entity recognition tailored to specific industries or use cases.

After training, developers can easily integrate the custom NER capabilities into their applications through the API.
